The third geology field trip along the city of Victoria’s shore has been added to the website. This one walks the city’s south shore along the Dallas Road waterfront trail from Clover to Holland Points. The trip description is largely the work of Gerri McEwen, who just completed her undergraduate honors thesis on these rocks at University of Victoria.
The relationships between these coast rocks are complex. There has been repeated intrusion, faulting,and metamorphism during accretion of an island arc and offshore terranes against Wrangelia after the latter giant terrane had collided with North America. Do you know the meaning of the terms ‘hanging wall’ and ‘foot wall’? Go to the Dallas Road field trip webpage to better understand the origin of these terms.
Some of the rocks are beautiful and well worth the visit. Take your camera!
